Non-Configurable Data
Down - This is the initial interface state. In this state, the lower-level protocols have indicated that the
interface is unusable. In this state, interface parameters will be set to their initial values. All interface
timers will be disabled, and there will be no adjacencies associated with the interface.
Waiting - The router is trying to determine the identity of the (Backup) Designated Router by monitoring
received Hello Packets. The router is not allowed to elect a Backup Designated Router or a Designated
Router until it transitions out of Waiting state. This prevents unnecessary changes of (Backup)
Designated Router.
Point-to-Point - The interface is operational, and is connected either to the virtual link. On entering this
state the router attempts to form an adjacency with the neighboring router. Hello Packets are sent to the
neighbor every HelloInterval seconds.
Designated Router - This router is itself the Designated Router on the attached network. Adjacencies
are established to all other routers attached to the network. The router must also originate a network-LSA
for the network node. The network- LSA will contain links to all routers (including the Designated Router
itself) attached to the network.
Backup Designated Router - This router is itself the Backup Designated Router on the attached
network. It will be promoted to Designated Router if the present Designated Router fails. The router
establishes adjacencies to all other routers attached to the network. The Backup Designated Router
performs slightly different functions during the Flooding Procedure, as compared to the Designated
Router.
Other Designated Router - The interface is connected to a broadcast or NBMA network on which other
routers have been selected to be the Designated Router and Backup Designated Router either. The
router attempts to form adjacencies to both the Designated Router and the Backup Designated Router.
。 Neighbor State - The state of the Virtual Neighbor Relationship.

link.
。 Submit - Send the updated configuration to the switch. Configuration changes take effect immediately. These
changes will not be retained across a power cycle unless a save is performed.
。 Delete - Removes the specified virtual link from the router configuration.
